PIN INSTRUMENT Filed June 28 1929 w a i Patent ed Aug. 29,1933

This invention relates to stripinginstruments, and more particularly ,to motor driven striping instruments. l a

An'object of the invention is to. provide an instrument for applying a stripe of paint or lacquer to a surface. i 1.

Another object of the'invention is-to provide an instrument for applying stripes'to'a surface where the use of a guide or straight edge is impossible due to the restricted space for operation,

Another object of the invention isto provide .an'instrument ,having a motor operated feed for delivering paint or. lacquer from a container 7 to. a nozzle, and means associated therewith for controlling the operation thereof.

. Another object of the invention is to provide a striping instrument 1 having a positive. feed means for delivering paint or lacquer from a container to the nozzleof theinstrument, and means readily accessible to the operator for controlling the feed means. 7

Still a further object of the invention is-to provide a striping instrument having a motor operated pump for delivering paint or lacquer from a the drawing, which forms a part container to a nozzle, and a brake for the pump having actuating means for v.varying the speed 'of the pump, or for stopping the pump as maybe desired in the manipulation of the instrument. A still further object of the invention is to provide a motor driven striping instrument which is highly eflicient in operation and yet of marked simplicity as a whole, and in respect to its comi ponent parts, so that its manufacture may be economically facilitated both regarding parts and their assembly. g Other objects of the invention willappear from the following description taken in connection with of this specification, and in which: 3 l

Figure 1 is a longitudinal sectional view of an instrument embodying the invention, v p z Figure 2- is a sectional view substantially on line 2-2, Figure l, and Y Figure 3 is a sectional view substantially on line 3'3, Figure 1.

Referring to the drawing for more specific details of the invention,'IOrepresents a sleeve having an inturned flange 11 providing an axial bore 12. The sleeve is internally threadedas indicated. at 13, and is provided with a boss 14 hav.-'

ing a bore .15. A container 16 is supported in the bore 15 and the'container is provided with a cap 17, having the conventional vent18p 'A' disk 19 positioned in the sleevebears against the flange 11. The disk 19- has formed integraltherewith a sleeve 20,- axiallybored as indicated at 2l-,.and mounted for-rotationin the boreisa shaft 22.;1Theshaft 22, issuitably connected to a spring motor 23 having theconventional windingkey24; Positioned in the :disk.19 60] is a passage 25.;leading from the bore to the intake port 26 of the pump mechanism, The ,pump mechanism is preferably of the gear type. comprisingf,agplurality of gears 28, one of 3 which is suitablyckeyed tothe shaft22. As shown, 65, l

the-gears-28 are mountedin, a disk .29., having overlapping; transverse .bores in which'theggearsare positionedginiintermeshing relationwitlrythe intake 30 registering with 'the port '26 and the outlet 31; registering with a 'passage 32 positioned in 70. a .disk 33which covers the pump-and thediski29- in which the pump ispositioned.

. The disks 19, 29 and .33 arelsecured; to each otherand to the flange 11 by means of a'pin' 34. This pin also secures in position anozzle 35., As 75 shown, the nozzle-35 is provided witha flange--36 which fits snugly inithe sleeve, 10,. and is. clamped therein together with the disks 19, 29 and 33 by means of a nut 37 threaded in the sleeve The nozzle 35 is provided withanaxial bore 8.0- 1 '38 adapted to register with the passage '32 com-'- municating with the outlet of the pump, and po- "sitioned,longitudinallyin the nozzlefor smooth reciprocation is a shaft 39 one end of which extends through the disk 33 and engages a face on 8 one of the gears 23. The other end of the shaft is loosely pivoted to prevent binding as indicated at 40 to a bell crank lever 41 having one end pivoted to the nozzleias indicated .at42, andthe other end engaging a coil spring 43 positioned in are- 9Q cess 44 in the wallof the nozzle. The shaft-39 is actuated by the spring 43 to bear upon one of the gears 28 with sufficient pressure to control the motor 23.. I

Inoperation, assuming that the container 16 is 9 V filled with-paint, lacquer, or the'like, andthatf .the motor 23 has been wound for operation; the

discharge end of the nozzle is applied to the sur- 1 face to be operated upon, and thelever 41 is actu-' ated by the thumb'or forefinger to disengage the shaft 39 from the gear; whereupon the motor im-' mediately. sets "the pump mechanism in operation to draw the paint orlacquer from the container 16 throughthe passage 25 to and through the" intake port, through the pump and discharges it -throughthe-outletport-32 and the nozzle. I

The'paint or lacquer is discharged from the nozzle in aE'constant fiowand as it is discharged,

the instrument is moved across the surface to be operated upon. 'It is to be understood'that the .11

speed of the pump may be readily regulated to discharge the quantity of paint desired by varying the pressure on the bell crank lever 41, or that the lever may be released to stop the operation of thepump. Hence the pump mechanism may be operated to deliver a-predetermined quantity of paint from the container tothe discharge end of the nozzle.

7 One of the outstanding features of this inven 7 tion is the provision of a striping instrument having a nozzle of small 'cross sectional area, per- 1 mitting operation-in restricted areas. xAnother' important feature is the means for controlling the operation of the feeding mechanism at a point readily accessible to the operator, and a further imp'ortant feature is the provision of an instru ment having a motor driven feedingmechanism.

Although thisrinvention has'been described in" connection with certain specific embodiments, :the

,principles involved are susceptible of numerous other applications that will readilyuoccur to persons 'skilled in the art. The invention is,therefore, tolbe limited only asindicated by the scope of the appended claims." I

Having thus described the various features of my invention, what I claim as new and desire to secure by Letters Patent is: i 1. A striping instrument comprising a container, a nozzle, a pump connected between the container and the nozzl'e, means' for operating:

the pump, and manually actuated brake means positioned on the'nozzle and'engageablewith the pumpfor controlling the operating speed thereof.

' "21 A striping instrument comprising acontain er, anozzle, a pump connected between the containerand the nozzle, a'motor for driving the pump, and a manually operated brake mechanism mounted on the nozzle and engageabledi rectly'with' the pump to control the speed thereof. 3.-A striping instrument comprising a container, a nozzle, a feeding means intermediate the 'container and the nozzle, a motor for operating the feeding means to deliver paint from the container to the nozzle, a brake mechanism for the pump positioned in the nozzle, and a manually operatedlever for actuating the brake readily accessible to the operator."

4. A striping instrumentcomprising a nozzle,-

a-pum'p associated withthe nozzle in a relation 1 to feed fluid therethrough, av motor connected to operate the pump, a brake element directly engageable with the pump,:and manually-operable 'mechanism carried by the nozzle and connected to control the brake element.

5. A striping instrument comprising a container, a nozzle, a rotary pump intermediate the container and the nozzle, a motor for operating the pump, a rod" carried by thernozzle and en- Lgageable with the pump to control the speed of rotation thereof, and'operating means connected with the rod, said meansbeing adapted to move the rod toward and away from the pump.

6. A striping instrument comprisinga nozzle,

a gear pump associated with the nozzle in a relation to feed fluid therethrough, a motor connected to operate thepump,an axially movable rod carried by the nozzle and engageable with oneof;

tion, 'a lever pivotedto the nozzle and to the rod,

saidlever being adjustable to move the 'rod axially, and a spring intermediatethe lever andthe nozzle exerting a force against the lever to normally place the rod in braking relation with'the pump.
